i Specification of Letters Patent.

Patented Dec. 10, 19] 8.

Application led May 6, 1918. Serial N o. 232,851.

To all whom t may concern: Be it known that I, HERMANALBERT WILL, a citizen of the United States, residing at Shirley, kin the county of McLean, State of Illinois,.have invented a new and useful Wrench; and I do hereby declare the f ollowing to be a full, clear, and exact description of the invention, such as `.will enable others skilled in the art to which it appertains ,to` makeand use the same.`

`.The present invention relates to certain new and useful improvements in wrenches, and has for its object to provide a device of this character which embodies novel features .of construction whereby'the movable jaw can be quickly adjusted and held in an adjusted position withoutthe loss of time which is incident to manipulating a screw member.

Further objects of the invention are to provide a wrench of this character which is comparatively simple and inexpensive in its construction', which is not liable to break orl get `out of repair, which can be quickly manipulated, and which can becollapsed ried in the pocket without difculty.

Withthese and other objects in view, the invention consists in certain novel combinations and arrangements ofy the partsas will fully appear as the description proceeds, the novel features thereof being pointed out in the appended claims. j

For a full understanding of the invention, reference is to be had to the following description and accompanying'l drawings, in which:- Y

Figure 1 isa side elevation of a Wrench constructed in accordance with the invention` showing the same as collapsed and in position for carrying in the pocket or packing away inthe toolchest.` I I Fig. 2 is a sideelevation of the wrench when in operative position, portions being broken away and shown in section to illustratel more clearly the details of construction. Fig. 3 is an end view of the two jaws of the Iwrench, showing the same as separated, the lower end of the handle being broken away.-

Fig. 4 is an edge view of the lower end of the tubular stock and upper end of the handle -extension, showing thel spring latch member fory locking the handle extension in an vextended position, w 4

' Fig',k s a transverse sectionalv view ou the line 5 5 ofFig. 2, showing the end of the tubular stock.

1 Corresponding and like parte are referred Y project beyond thestock when the tool is in use, as indicated by Fig. 2.` One side ofthe tubular stock is provided at the end thereof with a slot within which a spring latch arm 4, is fitted, the upper end of the latch arm being secured to the stock by a suitable fastening member 5, .while the lower end ofthe latch arm` terminates in aninwardly projecting nose 6 which is adapted to engage a selectedone of a series of openings 7 inthe handle 3. The bodyy portion of the latch arm 4: is flush with the outer surface of the stock 1 so as to avoid exterior projections, although an intermediate portion of the latch arm is crimped outwardly at 4a to provide a finger; piece which can be engaged by the f fingers when it is desired to spring the latch arm outwardly and move the nose 6 into inoperative pos`ition. It will thus be obvious that the handle 3 can either be telescoped into the tubular stock and housed therein, or

locked in a position stock so as to be used as a handle, as indicated by Fig. 2. The end of the handle 3 may be sharpened as indicated at 8 so as to be susceptible of being used as a screw projecting from, the

driver, if desired.

- A movable jaw 9 is slidably mounted upon the stock 1, being'shown as formed with a sleeve portion 9El which receives the stock.`

This law 9 is movable toward and away from thefiXed jaw 2, and the enol thereofv is longitudinally recessed or bifurcated to receive a block l0 which is pivotally mount' edy upon a pin 11. An integral pawl 1 2 is' pendent fromthe block 10 and constructed to"engage any/selected one of a series of notches 13 ini the adjacent face of the stock Il. A finger piece 14 projects from theswinging end of the pawl l2 and enables the pawl to be readily'inoved into inoperative position when it is desired to release the movable jaw 9 to slide the same away from the fixed jaw 2. The upperend of the block 10 is formed with a. flat side 10a which is flush with the gripping face of the movable jaw 9 when the pawl 12 is in engagement with one of the notches 13. It will thus be obvious that when an object such `as the nut A is gripped between the two jaws the pawl 12 will be locked Zin operative position and can not be disengaged from the notch 13, sinceJ the necessary swingingmovement of the pawland block 10 is rendered impossible by the engagement of the flat side 10a of the block with the nut. This is indicated quite clearly by Fig. 2. A coil spring 15 is interposed between the upper end Vof the block 1,0 and the base ofthe bifurcation in the movable j aw,- the ends-of the coil spring being received within suitabledepressions y16 which serve to .hold fthe .spring in proper position,l and the face ofthe spring ,normally serving to hold the pawl 12 -yieldably in operative position. The movable -.jaw kcan thus be moved freely 'toward the' fixed .-.jaw

in order to obtain the desired adjustment, the pawl `12slid1ng. over the notches 13, although retrograde movement of the .jaw is prevented bythe pawl unless the same is swung outwardly into an inoperative position. Howevenwhenan object such as kthe nut A is gripped ibetweenthe jaws it :is not possible for lthe pawl ito'beaccidentally swung into inoperative position and .the movable jaw released, since this swinging movement of :thepawl is prevented by the engagement ofthe fiatside i110a of the block 10 withfthe n ut.

When operatingupon aparticular size of nut or bolt lit kmay :be found desirable .to

- lock" the movable ,jaw 9 inan adj usted :position. `For ythis purpose .the `pawl y12 `may ybe slottedat an intermediate (point in itslength to lreceive a `disk 17, said disk being pivoted upon a pin 1S, ,and the forward side thereof projectingfthrough the front ofithe pawl where it is provided with a finger piece 19, whilethe rear side `thereoflis provided with a hookedarm20 adapted to .be swung into and `out of engagement lwith an undercut recess 21 formed yin the -base of the bifurcated portion ofthe mov-able jaw. Theprojecting portion of the' disk i17 can be readily engaged by :the '-*fingersgto rotate the disk a sufficient amount 4to swing .the hooked arm 20. into and yout of operative posi-tion. When the hooked ,farm is fin fthe position ,indicated by :full zlines von- Fig. 2 the locking device is inoperative and the pawl 12 can be swung outwardly andldisengaged 1.from the Anotches 13 .when desired.

` However, when .the 4hooked yarm yis lswung vHaving thus described the invention, what- I claim as new and desire to secure by Letters Patent, is

-1. A wrench including a stock having a series of-notches in one side thereof, a Xed jaw upon the stock, a movable aw slidable on the stock and having the end thereof bifurcated, a block pivoted in the bifurcation of ,the jaw, a pawl rigid with the block and adapted to engage one of the notches of the stock to hold the movable jaw inan adjusted position` a finger .pieceprojecting from lthe pawl, and a spring holdingthe pawl .yieldably in operative position, 'the block being formed with a Hat side which is yflush `wi-th the gripping face ,of Vthe ljaw when the pawl ,is in operative position, and cooperates with an object ,gripped ,between the j aws l.to prevent accidental. release .of the pawlwhile the `wrench is in use. l

2. A wrench including a stock having a series of notches in one side thereof, a fixed aw im thestock and having a .bifurcatediportion, an undercut recess being .provided .at the' face of the bifurcated portion, a :pawl pivoted on .the said ybifurcated` portion `*of the .jaw and adapted toengagea selected onehfthe notches in the stock 4to .hold ,the

jaw yin `an adjusted position, and aghooked locking arm carriedihy the pawl and adapted to gbe swung into engagement with .the before mentioned undercutrecess to lockthe pawl in an adjusted position.

3. A .wrench vincluding a vstock having a series of `notches in one side thereof, a fixed j aw4 upon .the stock, a ymovable ,jawslidable upon the stock and formed with axbifurcated .portion yhaving an `undercut erecess at the base thereof` a Tpawl pivoted Vwithin .the bifurcated rportion `of the .jaw and adapted to engage a selected one of the notches rkto hold :the ,j aw in operative position, and a disk pivoted upon the pawl and arranged with a portion `thereof projecting from'the pawl, said disk being formed with a hooked arm which can be swung into engagement with the before lmentioned .undercut recess to lock the pawl inoperative position.
